From the storm reports

Flash Flood · Jun 14, 2024. Thunderstorms developed along a stalled out frontal boundary, which was situated across the middle of Nebraska. As these storms tracked to the southeast, they became severe over southwestern Nebraska. Thunderstorm wind gusts up to 60 MPH were reported along with flash flooding between Lisco and Oshkosh.

Flash Flood · Jul 7, 2022. Thunderstorms produced torrential rainfall that led to flash flooding from the evening of July 6 into the morning of July 7 in parts of the panhandle as well as central Nebraska.

Flash Flood · May 18, 2018. An upper trough across the western CONUS and a remnant outflow boundary set the stage for a few severe thunderstorms.

Flash Flood · Jul 22, 2016. Continual development of thunderstorm clusters over the southern Nebraska panhandle led to flash flooding. Large hail and strong winds were also reported across parts of southwest Nebraska.

The zones you’ll see on the map

Every colour on the map above is a place on this drawing: where the ground sits relative to the flood FEMA plans for.

Cross-section of a river floodplainDiagram: a river valley. The floodway is the channel and the land beside it; the 1%-annual-chance flood surface (the base flood elevation) covers the valley floor as zone A or AE; a narrow band higher up is shaded X, the 0.2% floodplain; higher ground is X.0.2% CHANCE A YEAR (500-YEAR)BASE FLOOD ELEVATION · 1% A YEARXAEFloodwayAEX
  1. A / AE Inside the 1%-a-year floodplain: about a 26% chance of flooding over a 30-year mortgage. AE has a mapped base flood elevation; plain A does not.
  2. Floodway The channel and the land beside it that has to be kept clear enough to carry the flood. Building here is tightly limited.
  3. X shaded The 0.2% (500-year) floodplain, plus some levee-protected and very shallow flood areas.
  4. X Outside both lines. No federal requirement to insure, which is not the same as no risk.

Flood insurance in Garden County

If a building in Garden County is in a high-risk zone (A or V) and its mortgage comes from a federally regulated or insured lender, or is federally backed, flood insurance is required.

Outside those zones it is optional, and often worth having: from 2014 to 2024 nearly one-third of NFIP claims came from outside the high-risk Special Flood Hazard Area. Since Risk Rating 2.0, NFIP premiums are set for each building, so the only reliable price is a quote: FloodSmart.gov or a local agent.
